I would say we're not using them because (1) single stage rockets don't work very well, and (2) if you're using a two stage rocket anyhow, you're better off with a low altitude engine and a high altitude engine than an aerospike. I don't think it's really a lack of investment.

Now, call me a conspiracy weirdo if you wish. But the true reason this tech has never been fully realised; is because the alien crab people who use mind waves and contrails to control the government, won't allow it. But, once Jesus and John Wayne are risen. Then the true believers will build walls around anything they wish and there will be guns for everyone. Amen

I thought the engines work by the action reaction - the rocket lifts in a reactive response to a contained explosion like a shotgun recoil..interesting

is there any plans for a space ship fueled by its occupants yet? When you take 2 of every life on earth in your ship? you wont harness the animals? launch frozen dung at a propeller that fills your solar sail? or propellers don't work in space? dung freezes in space, doesn't it? make your frozen poo and farts in to depth charges that explode behind your ship instead of mini nukes

The mankind should use a plasma hydrogen engine, the conventional engines burn very fast this liquid hydrogen, and are not a very eficient engine,The humans should does recreate the sun fusion there ,the hydrogen plasma appear only when the hydrogen fussion and that happend only when we can produced a huge pression and temperature some a milion half grads, that are the temp when the hydrogen does fussion in fotons ,the china work of one type of this plasma hydrogen advanced engines ,they work been long time to does development a new prototype engine.Were be very hard for all the world nation when they were be cappable to does builded, this first super engine , what are cappable to go to another star systems, they could does recreate a litle star , what could give unlimitated energy for them star ship engine ,very cool greetings from dracula country !

Money remains one of the main driving forces behind technological evolution, and money remains one of the main stopping blocks in the way of technological evolution. Until we grow up and start doing things for the betterment of humanity and the planet, rather than worrying about archaic principles like money and profit, we're more likely to die out as race than ever achieving anything significant, much less anything that will even warrant a footnote in the greater cosmos.

Just thinking here... wouldn't efficiency also translate to weight? I mean the more efficient an engine is, the less fuel you need, so the more weight you can carry, thus the more profits you potentially can bring in. So aerospikes have a legitimate reason to be developed outside of fuel cost. Couple that with the extremely expensive and wasteful habit of disposing of multistage rockets and rocket boosters, and aerospikes sound even better from an investor's perspective.

The problem is weight. You need to discard useless masses as soon as possible. So, aero-spike ends in an useless concept in a multistage rocket. Single stage to orbit rockets (SSTO) would be a VERY mass inefficient one.

The pace of propulsion research is speeding along so quickly, by 2025 we'll have advanced plasma propulsion and nuclear fusion engines that can get us to Mars within a few weeks! Such research is occuring now at the JPL in the USA, where a combination or hybrid fusion-plasma rocket engine is in the works and a mere couple of years away in completion. The speed of such engines is exponentially faster, where interstellar suddenly no longer looks out of reach.

I've always been fascinated by pulse detonation engines. Research was hindered because the materials required had simply not been invented yet, and of course computers were in their infancy so modelling wasn't possible. Still it would be quite incredible if someone developed a working engine based upon this principle.

I couldn't watch all of this gibberish. Rocket engines *do not* rely on air pressure at any altitude. Newton's laws of motion and conservation of energy proved long ago how rockets work. If air pressure had any influence (other than drag) rockets couldn't work in a vacuum, but we know they do. The Aerospike may be more efficient, but not to the degree he claims. As for his single stage rocket: That wouldn't work with any fuel that we have currently or any we can envisage having in the foreseeable future. Multi stage rockets aren't built to use different shape rocket nozzles, but to keep the dead weight to a minimum by ejecting it as soon as the fuel tank is empty. It's all just smoke and mirrors to hide his lack of understanding of physics.

+Gagarinone I wasn't intimating that I could do it better, but that he grossly overestimates the improvement over the bell shaped combustion chamber. And that he ignores the weight being dragged into orbit even if it could work. Which it couldn't. NASA and the rest of the aerospace industry know about this modification, and have done for decades. Isn't it obvious that if it gave them a significant advantage over current technology that they would be using it to put ever heavier objects into space?

Would one gain a further advantage by flying the rocket as high as possible supported by high lift wings and using air as the oxidizer. Liquid oxygen would only be used at altitudes where the air was too thin to be used as the oxidizer. You reduce hugely the weight that must be lifted off the ground in the first place and use relatively cheap jet fuel as your energy source. You could even drop off the wings and their framework to glide back to earth. This unit could be flown from wherever the launch site is toward the equator as it gained altitude to take advantage of the approximately 1000mph speed of rotation of the earth.

Basicaly they make engine go soft enough to not waste power pushing through air, like walking gently enough on ice lake surface to provide propellent, but not too hard that your foot smashes through ice & then you start falling down.... & with different levels of surface strength depending on atmosphere pressure/height, just like different levels of lake ice surface strength depending on how thick its ice sheet is/depth. You know it's be easier if they just had a very big broad afterburner engine to ensure maximum softness/useful working thrust, & then just add a squeezing mechanism to close opening & increase thrust power if necessary...

this question can be summed up in one simple answer................................. MONEY! they ran into huge over runs and they didn't even have the fuel cells developed, you are compromising power with this setup so fuel cells must be lightened and still hold up, trus tme when this rock is no longer inhabitable cuz the air is so wretchid, the water is all polluted and radiation levels astronomical they will develop these engines and them some, man will achieve intergalactic flight for sure, has to or he is done, he destroyed this planet already and its irreversible, wait till he starts to suffer the ramification of drawing all the crude and gases from the earth without replacing it with anything? earth quakes, tsunamis, rising sea levels, all child's play when all this comes into play, i'm talking huge continental plate shifts, greed ran won the day and still does,m no one did any studies when they extracted the earths resources, they just did it, in any crude manner that suited them, fracking and all sorts of bio hazards means, simply for the love of more money than anyone could possibly ever spend in a 100 lifetimes, yet they still did it.. claiming "we need to do this" morons, all of them, sink holes, you ain't seen nothin yet... BTO... wait till the plates have to fill voids and so forth, things enter the voids that shouldn't.. entire counties sink, states.. mountain ranges topple over... yup, just keep sucking the shit out get your greed on of course it wont be those simple fucks who endure it, they will be long gone, people are so confused by the saying "and the meek shall inherit the earth" what that means is if man is meek, and lives life within the proper terms he shall live on this earth and "inherit it" for a long long time, however IF man is not meek yet GREEDY SELFISH and CORRUPT! he will NOT inherit the earth and it will be destroyed sooner than later" it has nothing to do with God, or anything else, its just common sense...

Aerospikes aren’t magically much better... On a planet like Earth, where SSTOs are very difficult and expensive to make, it is much better to use a two-stage rocket with bell engines. I would argue it’s even more efficient (at least from what I have been working on). If you want an SSTO for whatever reason, and you can make the engine light enough, an aerospike is absolutely better.
